It was printed with Raise3D premium white PLA, the settings are the raise3D Speed Template on a glass bed at 80 C. I can't look up the exact settings until I get I to work tomorrow, but the only change is the bed temp and added M201 X500 Y500 to the start gcode. I found the top surface covered well with no support. Printed with the printer top removed.

Mine spends all of its time making prototype parts for a new 3D printer. Because all of the parts of my printer are all machined or custom weldments, mistakes are expensive. So, I use the N2 to "rough draft" before I machine. So much cheaper. On the main gantry bridge weldment, I will be taking the best three designs from FEA analysis and printing them off and then printing off a deflection test fixture and determining which has the stiffest structure for the least cost. Printing prototypes has helped me make a lot of revisions that were immediately obvious when I printed them. Little things like adding three threaded hoist rings so I can lift the gantry of the new printer with an overhead crane while aligning the linear bearings. I would like to do the Medusa as a test print on the new machine when it is complete.
